Commonly used gas flowmeters include: vortex flow meter, gas mass flow meter, differential pressure flow meter, thermal flowmeter, volumetric flowmeter, float flowmeter, ultrasonic flowmeter. What are the differences between these flowmeters? How should we choose? What is their price? What kind of gas flow meter is suitable for my current situation?

 

Vortex flow meter: It uses the vortex principle to measure gas flow and has the characteristics of high measurement accuracy, good stability and fast response.

 

Differential pressure flow meter: Calculate the flow rate by measuring the pressure difference generated when the gas medium flows in the pipeline. It is suitable for various types of gas media. Orifice plate flowmeter is a widely used type of differential pressure flowmeter. By setting an orifice plate on the pipe, when the gas passes through the orifice plate, a pressure drop will occur.

 

Thermal flow meter: uses the principle of heat conduction to measure gas flow. It has the characteristics of wide measurement range, high precision and good stability.

 

Mass flow meter: directly measures the mass flow of gas media, suitable for various types of gas media, with high measurement accuracy.

Volumetric flow meter: Calculate the flow rate by measuring the volume occupied by the gas medium flowing in the pipeline. It is suitable for measuring low-viscosity gas media. Roots flowmeter is a type of positive displacement flowmeter. There is a fixed large space inside and a set of rotating bodies that divide the space into several small spaces with known volumes.

 

Float flowmeter: Uses the float principle to measure gas flow and is suitable for measuring small flow gas media.

 

Ultrasonic flow meter: The detector measures the propagation speed of ultrasonic waves in the gas to calculate the gas flow rate. The transit-time ultrasonic flowmeter is one of them, which works based on the difference in propagation speed of ultrasonic waves in the flowing fluid along the downstream direction and the counterflow direction.

 

In addition, there are also types of gas flow meters such as velocity flow meters and vortex precession flow meters. When selecting a gas flow meter, you need to consider various factors such as the type of measurement medium, measurement accuracy, pipe size, and working environment.
